CPC H04B 7/18513 (2013.01) | 20 Claims |
1. A mobile terminal for enabling radio communications using software controlled mapping of frequencies, the mobile terminal comprising:
a common reference device configured to provide a common reference signal for frequency conversions;
frequency conversion circuitry configured to use the common reference signal from the common reference device to perform a frequency conversion of incoming and outgoing communications, the frequency conversion circuitry including an uplink communication signal path by which one or more outgoing communications are converted from a mobile frequency to a transmission frequency and a downlink communication signal path by which one or more incoming communications are converted from the transmission frequency to the mobile frequency, the mobile frequency being in a VHF or UHF frequency range, the transmission frequency being in an L-band or S-band frequency range; and
pilot tracking circuitry configured to determine a frequency error based on a frequency of a received pilot signal and cause an adjustment to the frequency conversion performed by the frequency conversion circuitry based on the frequency error.
